[Q] Possible hardware problem of the back button?

I just wanted to share this, since I was able to replicate this issue with three different phones, also asking if other people are having the same issue.
I am using my Samsung Nexus S for three days.
I noticed that the back button (the first capacitive button on the bottom left) appears to have an hardware problem.
Basically normally it works fine, I mean when I'm not using the phone for some hours.
Then if I start to use the phone, after a moderate use (example installing applications from the market, browsing etc) the button gets less and less sensitive.
After some minutes it gets really annoying.
To make it work it is necessary to use a really stronger pressure with the finger, and it is not even always working!
I am planning to return my device, but today talking with some people/colleagues I discovered that two of them have exactly the same problem.
I'm suspecting there is a batch of Nexus S phones with this glitch, I am curious to know how many people have the same problem.
Note:
At first I thought it was a general issue of the capacitive buttons. But I can't replicate the same problem with the other three buttons, they work very smoothly just lighltly skimming the finger over them, even after long usage.
Anyone with the same problem? What is your experience with this button after some usage?
Cheers

I want to say that I noticed something similar the other day, but it was short-lived, and I'm not 100% sure. It wasn't long enough or bad enough to make me think the phone is defective, but I'm a bit used to funky capacitive button responses from my N1 days.
I can't reproduce the issue right now, though. How much usage are you talking about needing to duplicate?
Does your phone get hot, or feel hotter than normal when this happens?
I'd see if there's some particular pattern or software that seems to trigger it if you're interested in trouble-shooting.

The problem goes away when I don't touch the phone for a while (it seems that 1 hour is enough to reset the problem).
It seems "recharging".
Then with normal usage, nothing in particular, just even browsing in the settings/maps/market/browser etc., in few minutes the problem appears. The button definitely loses his "power".
It's very annoying, and my friends confirmed the same behavior.
EDIT:
Forgot to sat that the phone is not getting hotter, everything else is really normal.
Cheers

Mine definitely can be used for much more than a few minutes without the problem you're describing appearing.
I'd take it back. Factory reset the phone to protect your private data before taking it back. After the factory reset, you might want to test the behavior again, if it went away, the phone's not defective, you just had some software glitch.
Reminder, factory reset erases everything on the phone, so if you do it as troubleshooting step, be prepared to have to set the phone up from scratch again...I'm sure you knew this, but just covering my butt in case you didn't. It's a good trouble shooting step no matter what if you don't mind the hassle of re-setting things up.

I have a similar experience with the back button. Not sure what to think yet.

I had a similar problem when I had the Vibrant. Just exchanged it and luckily I got a better one without any problems. I did find out though if you are using the screen protector that came with the phone, it can cause this type of problem.

No problem, I will try everything tomorrow. This is not my primary phone (still loving my rooted Nexus One with CyanogenMod 6.1.1 ;-) I can't renounce to the colored trackball for the different notifications), but just a "dev" phone for testing purposes.

The app NOLED from the Market may interest you if you can't live without trackball style color notifications. Seems to work fine when I tested it.

Thank you, giving it a try.
Anyway, today I factory-reset my telephone and the problem of the back button is still there. I am returning the device.

Back button non responsive
Hi,
I just got my new nexus S (about an hour ago) that I was really excited about and am faced with a problem with the back button too.
Its got factory settings, so it cannot be a downloaded software issue. Also, I have not yet charged the battery at all, its still running on the same battery power that it shipped with.
The other buttons at the bottom of the phone (home, menu and search) all respond fine, its only the back button that does not seem to work. After going through this thread, I tried long-pressing the button, hard-pressing it, pressing just above it, below it, etc. It just wont respond. I had removed the screen protector it shipped with, so that cannot be the issue either.
If this is a known hardware problem (i.e. others have faced it too), irrespective of whether it is acknowledged by Samsung / Google, I'll return the handset. I do not want to spend a fortune and be landed with a handset that does not work - forget working as desired, but it does not seem to be working as designed !
Thanks & Regards,
Rohan

Yep. Definitely a problem here with the back button. There's also two other threads here about it.

I'm having similar problems. I have to touch the button just right for it to work properly

I was experiencing the same thing with my Nexus S, wasn't sure if it was the case I was using! Took of case and still had problem. I eventually returned mine cause it seemed like it was getting worse! I have a new one worth no problems, definitely a hardware problem! Return it!

those buttons work over the heat of your finger. thats why after use it doesnt get as responsive. its because the screen is also heated and the heat of the screen is effecting the buttons. thats why you need harder pressure for the phone to understand this is your finger.
same issue was with Nexus 1. less responsive buttons. thats why there is a bigger gap between the buttons and the screen for galaxy S phones. i dont know why they did such a thing again with the nexus S. its like samsung didnt learn from anything from HTCs mistake.

They work with capacitance, not heat. Hence it being called a capacitive screen with capacitive buttons.

I think this is true ...
I have an HTC Desire with AMOLED screen.
When I play a finger intensive game, like "SkyForce Reloaded", after some times, the touch is not registered.
Then I must stop for a while, or change finger
Try that, you will know what I meant.
But, I don't have issue with the back button on HTC Desire because it is a hardware button. I am just trying to explain about loosing touch registration because finger interaction on (s)amoled screen.
PS: SkyForce Reloaded is an old school shot'em up game where you control a little space ship with your finger, shooting enemies.

The Desire's digitizer is the same Clearpad 2000 which is used in the Nexus One (and quite a few others), the problem there is that it's pants.

lol, isnt called like that because it registers the heat from your fingers. thats why if you try to use a pen, it wont register . and thus. the screen is NOT resistive type "where it will recognize anything since its being pushed by force ? "

Much more too it than that: http://en.wikipedia.org/wiki/Capacitive_touch_screen

from your link
"A capacitive touchscreen panel is one which consists of an insulator such as glass, coated with a transparent conductor such as indium tin oxide (ITO).[7][8] As the human body is also a conductor, touching the surface of the screen results in a distortion of the screen's electrostatic field, measurable as a change in capacitance. Different technologies may be used to determine the location of the touch. The location is then sent to the controller for processing.

[Poll] Do you have problem with your touchscreen?

I just got the 32G version transformer. There is a very annoying problem with the touch screen: sometimes it is not registering my touch at all, sometimes it seems that you have to push hard.
I am not sure if this is the touch screen problem or the system is busy with something else?
Anybody else having the problem? Any ideas to solve it?
The firmware is the latest version.

I too have noticed this issue from time to time. Not sure what it is though.

The touchscreen does seem a bit insensitive on my 16GB TF. Not necessarily unusable, but sometimes I have to touch a button a couple times to get it to respond. Most often the menu button that appears in the top right corner of some apps.

I am pretty sure this is a software related problem. Sometimes, the touch screen feels quite responsive.
What is the official way to report problems to ASUS?

Indeed. The touch digitizer and even it's driver works flawlessly - start Fruit Ninja HD and you can enjoy most responsive multi-fingers (4 or maybe more) touch ever.
But everything except games is considerably less responsive to touch.

The touchscreen on mine just completely died. Completely not responsive. I wish I could blame it on a faulty app or something simple but I put it to sleep and when I woke it 20 minutes later, I can't do anything with it. It responds to all the physical buttons just fine and the screen rotates and everything but it just doesn't respond to any touch.

I just installed Fruit Ninja HD. Although I am a newbie in cutting fruits, I am pretty sure the touch screen just doesn't register sometimes, even in Fruit Ninja.
My firmware build number is: HRI66.US_epad-8.2.3.9-20110423
Coming from Xoom, although the TF's IPS is much better than Xoom, but the touch experience of the TF is much much worse.
Sometimes you have to press hard and longer to register, I am wondering if there is a way to change the touch screen's sensitivity?
Whatever reason it is, it should be very easy for ASUS to reproduce the problem and fix it!

Try the app Multitouch Test in the market. It seems to be a lot more sensitive than some of the other apps are (or even the OS) regarding touch sensitivity. (Or at least it seems to be)

Thanks. Downloaded and tried.
When it's normal, it can track 10-finger touch easily. However, the main problem seems to be the response time for repetitive touches. The system seems to be not able to keep up with normal typing speed touches. It will register several touches, then non-responsive for a while. If you wait a while, like several seconds, it will respond again.
Is there a good APP to check CPU settings and utilization ratio?

What do you mean by cold reboot? I have reset it a few times by holding down the power button.

Interestingly, this thing is mentioned in Engadget UK's review (http://hartantolestari.info/search/asus-eee-pad-transformer-screen-is-not-working)
A lack of responsiveness is also evident throughout the Android UI. Aside from a delay in activating the function you’ve selected, there are also troubling instances where input isn’t registered at all. That leaves the user with no less than three potential scenarios when she doesn’t see an immediate response — she could be looking at lag, an unregistered tap because of software, or an unregistered tap because the physical input was too light. Such uncertainty doesn’t build a great user experience and the Transformer, unfortunately, doesn’t offer a great user experience. Much of that is, regrettably, down to Honeycomb itself. It’s not a finished product yet. It’s actually a fair distance away from a finished product. Some apps are done to absolute perfection while a lot of the “glue” bits, the stuff that goes between the apps and basically makes up the OS, is either confused, not responsive enough, or broken in some other way. Let’s take these things in turn, starting with the good parts.

I would reccomend against pressing hard. That is a good way to damage the lcd panel and the digitizer hardware. Capacitive screens dont register pressure just electircal conductivity from skin touching the screen. I would say any lag you are seeing is most likely software based as others have said.

Hmm, I have tried rebooting the device many, many times and still no change. I wiped user data hoping it would help (nope). I just don't understand why the touchscreen would stop being responsive to any input. It wasn't jostled around or treated badly in any way. I just had it in my backpack, which I was carrying by hand and the Transformer was in a padded compartment.
Overall, I am rather disappointed and disillusioned with Asus. The Transformer's terrific when it works but I've had to deal with the deep sleep issue at least once a day and then to have the touchscreen go dead entirely is terrible. The first I can see being a software issue that can be fixed but the second is probably shoddy hardware.

Cold reboot is holding power button until TF shuts down, ignoring shutdown dialog.

almost seems as if they didnt test the xoom. it feels faster than the tf bc its screen is more responsive.
i wonder if the screen could be calibrated manually with the config.ini lie the nook color.

Here is some update: after the TF slept for a night, I pushed the power button. The touch screen is just not responding at all on the lock screen. I let alone the TF for half an hour or so, pushed the power button again, now the touch screen worked fine. Unlocked and into the home screen, no problem with touch for about 30 seconds, then it becomes intermittent again.
I will call ASUS support tomorrow. Hopefully there will be some firmware update very soon to address this, otherwise, I will have to return it.
The weird thing is that if this is a software/firmware issue, lots of people should have reported it.

OK, I have created a case at vip.asus.com/eservice/techserv.aspx
Looking at some Youtube clips reviewing TF, their touch screen seems to be fine. So this might be a bad unit. I will return it next week (bought from local Fry's) and hopefully they have replacement units!

I have created a vote regarding the TF's touch experience.

Good luck! I got mine from Amazon and they are completely out of stock. The only option is to get a refund since they don't have an expected in-stock date so the CSR can't put a replacement order in for me. Every online retailer I've looked at is also OOS. Hopefully more come in soon.
I also spoke to Asus and they are willing to repair mine but not to give me a loaner or just outright replace it. That is really too bad. I was hoping they would be more like HTC, which has great customer service in my experience and gives out replacements at the drop of a hat. If the Flyer wasn't such a POS, they would have had my business.

[Q] Major problems with Sensation screen

Having problems with the touch screen on my sensation and this has now happened on my secound phone! both phones were ok out of box but after a few days first noticed problems from lockscreen as phone would not always unlock when draging app icon into circle then slowly geting worse until would take several swips on screen to even unlock! then started noticing similar problems in norm opperation? sometimes works ok but some times freezes up have tried factory reset and no differance. very strange having this problem on two phones?

Does the touch screen stop working completely?
Mine did that on Monday, had to get a replacement.

it seams to stutter once awake works slightly better? but still not responsive

I've noticed that the proximity sensor and gyroscope are being used aggressively to filter accidental screen presses.
For example, if I place my sensation flat on a table, the lock screen is very hard to unlock. If i place my other hand near the proximity sensor at the same time (or tilt the phone towards me) it unlocks easily. Until I identified this functionality I was beginning to think my right index finger was unsuitable for touch screens (since when placed on a table I tend to use my right hand, but otherwise use my left to unlock).
Hopefully this will be tweaked with future updates.

Many thanks I hope itd that simple?

I am having the exact same problem, for example on the lock screen I would swipe up but the ring will move slightly, and one icon I.e the camera icon will move towards the ring, another grip which is buggin me is that it will miss screen taps, I.e when texting or clicking an icon one tap will go unnoticed by the device resulting in either a missed letter, or the app not opening. This also goes for the 4 command buttons at the bottom, it happens on these too. I also get the occasional lock up.
Factory reset did not work

All of you are you using Sense, and no other launcher?

As I stated before, I experience this problem but it only occurs when the phone is laid flat and my hands are well away from the proximity sensor at the top left of the screen. I can say that the part you are describing with the lock screen is 100% the same problem I come across in certain situations.
Please test to see if the problem is still present when the phone is tilted in your hand and, if you are laying the phone flat when you experience the problem, try putting your other hand near the proximity sensor when you try to unlock.
If this happens as I describe then it is most likely a software bug which only affects users who have particular phone use habits.
Saying that, as you are having quite severe symptoms, during general use, it may be that you have a faulty proximity sensor in your phone - leading to missed screen taps when the phone thinks you are not touching the phone.

Well I laid the phone flat and unlocked it no less than 20 times, each worked flawlessly no problems at all..... Seems to have me baffled

Yes I've been having the same problem. First noticed it when trying to unlock it (phone was lying down), couldn't get the circle to move. Have had one complete touch-freeze. No input possible, however volume and power button worked. Took the battery out, restarted, and it worked fine.
I notice that input can be difficult sometimes, hit and miss or just have to push harder. Strange. Seems like a software issue to me.
edit: just had the same issue - circle wouldn't move. After picking the phone up I was able to unlock it, however still not as easy as it should be, a bit jerky.

Both my evo and my g2 had a grounding issue, for example if I had the phone laying down on the couch or bed, the screen would not respond to touch but if touch the phone with a finger and try to unlock it with my other hand it would work normally. So it seems to be a common problem with some HTC devices

The wildfire (my friend's got one) has this problem too. You have to keep touching the metallic housing for it to detect any taps.

You are correct, aim1126. I never considered grounding to be the cause but after re-testing it clearly is.
I guess it is a side effect of having a conductive unibody. So basically there will be no software fix, we just have to keep constant contact between our hands and the unibody. I wonder whether a rubber bumper would actually make this problem worse?
Edit:
Actually, the screen seems to adapt to not being grounded properly after a couple of presses. It works fine for me by the third time I touch the screen - weird. Well at least it is only a minor annoyance!

My wife uses a G2 and I wouldnt call it a grounding "issue" honestly seems like more of a feature to make sure you ment to engage the screen.. Its kinda cool IMO
As far as the screen being laggy this sucks since I wanted to upgrade from my Vibrant to the Sensation.. I also am not sure its a software issue you guys are having.. I am running Sense 3.0 with gingerbread on the G2 and it is very smooth.. The option to silence a call or tirning on speaker phone by turning the phone over is neeto torpedo..

I'm having the same issue, from lock screen I drag the circle up and it just stutters. After a few tries it usually works, once unlocked the touch screen appears to work fine. I'd expect the issue would continue after unlock if it was a hardware issue.

That's very bad. Flaky lock screen is not good, and the example of not being able to scroll through apps without it running one is a killer. There are many times when scrolling through a list of selectable items is necessary.
Are you going to exchange the phone?
Have my hopes set on the Sensation, so would really like to find out what the resolution is.

[Q] Sensation XE hardware keys and touch issue

Hi, I have a sensation XE that i S Off-ed and rooted using FloWolf's EXCELLENT guide before installing CM 10.1-20130322-Albinoman887-pyramid. However, i started facing the issue of the hardware keys giving feedback when touched, but not working- instead, it happens as if the lowest part of the display, right above the key i pressed, has been touched. I updated to the 20130510 nightly but it did not fix the issue. I now want to try going back to the stock ROM but can't find an easy guide. I never took a backup of the stock ROM with CWM . I have the HBOOT 1.29 model
Now another issue has sprung up. Even when using a single finger, the phone sometimes behaves as if i'm multi-touching it. It only gets fixed if i lock and then unlock the screen.
Will going back to the stock rom fix these issues or will i have to get it repaired? If the stock rom will fix it, can i please get a link for it that's as easy as Flo's guide to rooting was. Thanks!

I am on ICS 4.0.3 and Stock ROM.
Since last few days, I am having somewhat similar touch screen issues after the warranty of my Sensation XE expired last month.
At any given random time of the day, my touch screen goes berserk....!!! I am using Apex Launcher and have folders containing various apps in the Dock. These folders start moving around/rearranging automatically, apps start opening randomly on their own, screen and navigation keys (red ones on bottom panel) become unresponsive, keyboard comes up on its own and characters appear as if being typed... etc. If I lock and unlock the screen (all hardware keys - volume & power - work fine during all this), touch screen becomes responsive again but only for a short period. Again the whole cycle repeats. The only way to stop this for longer period of time is restarting the phone. This state last upto anywhere between 6-10 hours be fore my phone acts up again. I have tried the Factory Reset too, but with no results.
I have installed Avast Mobile Security soon after I got my XE. I have also installed around 80-90 paid as well as free apps.
Currently my XE has free resources as follows:
RAM 640MB out of 1.1GB
SD Storage 25GB out of 29.71GB
Though the behavior looks like some kind of virus activity, Avast doesn't show any malware or virus on the system.
Which issue does this behavior pertain to, a hardware or a software issue?
Any kind of help to pinpoint the cause of this issue is greatly appreciated.
Thanks & Regards.

Hello,
I am having the exact same problem as the two mentioned above. Sometimes the thouch screen doesn't response at all, start doing things by itself or the capacitive buttons on the bottom doesn't respond. To fix the problem I have to press the on/off button to lock and unlock the phone but after a minute it's going all over again. I thought this maybe could be a memory problem, as if the phone simply hangs because it is acting very slow when the problem shows up.
Last weeks I've tried many ROMS as I thought it would be a mem problem. Cyanogenmod 10.1 and 10.2, ViperS 1.6.3 and 3.1.2, Android Revolution and with all these ROMS the same problem showed up. So I'm thinking it's almost for sure that this is a hardware problem. I got my Sensation XE in January 2012 so there's still a waranty of a half year. In case this is a hardware problem I'm thinking about sending the phone back to HTC, but I'm not sure about what is causing this problem.
So, if anyone knows the cause of this problem, please share It's really annoying and makes the phone pretty much unusuable. In October I will be able to get a new phone but it would be nice to have a very good one for spare
Thanks in advance!

I thought this maybe could be a memory problem, as if the phone simply hangs because it is acting very slow when the problem shows up.
Last weeks I've tried many ROMS as I thought it would be a mem problem. Cyanogenmod 10.1 and 10.2, ViperS 1.6.3 and 3.1.2, Android Revolution and with all these ROMS the same problem showed up. So I'm thinking it's almost for sure that this is a hardware problem. I got my Sensation XE in January 2012 so there's still a waranty of a half year. In case this is a hardware problem I'm thinking about sending the phone back to HTC, but I'm not sure about what is causing this problem.
So, if anyone knows the cause of this problem, please share It's really annoying and makes the phone pretty much unusuable. In October I will be able to get a new phone but it would be nice to have a very good one for spare
Thanks in advance!

Put a thin foil between the metal pin on mid right and the back case.
Also search for touch screen issues in sensation forum. A lot of people have this issue.
Happy to help.

Thanks a lot Far_SighT for pointing me in right direction.
As per the "Touchscreen Issues" topic in "General" category, my phone will be undergoing second cycle of "Pull Pin - Add Tin Foil - Drain Battery - Take out Battery - Press Power - Keep Battery outside overnight - Recharge fully without touching screen" procedure.
First cycle didn't help much, but as per the post I have to go through this cycle at least 2-3 times.
I will get back with the results.
Thanks & Regards.

Update:
Followed the steps in the "Touchscreen Issues" thread under "General" category, and it worked!!
All my touchscreen issues have been solved by that simple solution. A great post!!
Highly recommended for solving similar touchscreen issues, specially when you have dropped your phone.
Thanks & Regards.

Can you elaborate which step you think fixed the issue of having to press the power button to make the screen responsive? I went throught a full battery discharge-leave overnight-full charge without touching the phone, but i did this procedure only once and didnt have the patience to try again as it didnt improve the situation at all.:cyclops:

Please follow my last post in "Touchscreen Issues" thread: http://forum.xda-developers.com/showthread.php?t=1239238&page=50
Mostly one cycle does not help as per my experience. I had to go through 3 complete cycles to get my XE fixed. It made huge difference only after second cycle.
Also, other than aluminum foil over the silver square on the side of back panel, place a piece of thin paper in the depression on the back panel (check the second snapshot in above thread) which should cover the metal casings of both SIM card and SD Card so that they do not touch the back panel.
The steps taken in the cycle after placing the foil and paper:
1] Drain the battery fully.
2] Remove the battery.
3] Press Power button as if trying to power on your mobile.
4] Leave the battery out for overnight.
5] Replace the battery and back panel taking care to see that both foil and paper are in correct positions.
6] Recharge your phone fully without touching the screen and without powering on (this to prevent you from using the phone. ).
7] Disconnect the charger and use your phone till battery drains out and phone is ready for next cycle.
Hope this is helpful to sort out your issue.:fingers-crossed:
Thanks & Regards.

Thanks for the tip but did that already. I read the OP well and a lot of pages in this topic but no luck so far. Stopped even trying because half October I will have a new phone, the One to be exact. So it's no use.
What I did try was the recalibration of the touch screen by flashing the image file. That worked for a few days maybe and now it's drama all over again. Sometimes I pull out the battery for a night, push the on/off button blabla but no luck too. I think it's actually half broken because on some spots on the screen it's registering no touch. I do have to admit my phone fell a couple of times past 2 years, without a case or something. So I guess for me the only option is a new digitizer.
Like i said, I really would like to have a good spare one. Went looking on E-Bay and for 16 dollars I found a digitizer for the Sensation 4G. I have a XE, will that work with that digitizer? A digitizer for the XE was 23 bucks, but if only the color of the capacitive buttons are different I don't care and I save 7 bucks
Thanks!

Touch screen problem

Hi guys,
i'm having an issue with my HTC u11, basically when i'm using the phone randomly the swipe down screen (when you swipe the screen down from top to bottom to get the notifications) comes down.
For example if while i am writing a message then drop down screen will come down when i'm typing, i then have to swipe up and continue and again.
it happens more or less all the time and is quite annoying.
any ideas?

its okay, issue resolved. NOVA Setting had gesture switched on. Swipe down for notification menu, this was the issue. lol
PLease close the thread.
Thanks

Well i had the same issue. Was driving me mad! Thanks for the info.

I don't use nova and I have been experiencing this same problem so now what?
Sent from my SM-G955U using XDA-Developers Legacy app

Yeah i though the Nova setting had solved it but it seems to be back again for me, although not as frequent.
I also experience the keyboard collapsing randomly too. Anyone get that?

Hi guys, thought nova got rid bit guess not. I still get the issue. Would this be a software issue or do I have a fault with my hardware?
Any tests I can do?

I reported my issues to HTC and they replied with the following :
To test the function of the touch screen please follow the below steps
1- Dial *#*#3424#*#* > the press accept.
2- From the options, mark Line drawing test > then press run.
3- Then start drawing on the screen to check if there are parts that do not respond
The screen does not have any dead or unresponsive spots tho and the test passes without any issues.
Does anyone experience the keyboard collapses also?
I might do a full reset soon to see if that helps any. If not i will be getting back in touch with HTC.

Did all this as well, and all the tests that I've ran pass just fine. I've also done a hard reset and it didn't make any difference. I do notice that after a soft reset that it takes a while for it to happen again. It's annoying as hell so I will be monitoring this thread. Whatever you find out from htc please update this thread so we can figure out what the hell is going on.

I also done the test and it was a pass.
I'm certain it's something to do with the software of htc. The UI has to have something wrong with it. Mind you it hasn't done it to me today yet and I'm nearly at the end of the day.
Has everyone got a case? Can't be case interference?

I turned off edge sense, I removed my screen protector and removed the case. It still does it when it's ready.

Exactly same issue here. Very very annoying. As a HTC fanboy I'm quite dissapointed. Phone less than 2 months old. I actually spoke to HTC today, they said they would have to book it in for a repair... Takes up-to 10 business days... I said this is not acceptable! Waiting for a email back.

I have emailed HTC back advising them that others are reporting the issue so unlikely that it's a single handset issue.
Awaiting their reply. No doubt it will be along the same lines that @dobknobby got and have to go through the 10 day repair process.
Will update when I get a reply.

I have had the same problem, and I have done the a lot of the same steps;
I tried several different screen protectors, thinking that was causing the issue. I have had no screen protector on for the last week, and yep it still happens.
Shut off edge sense, still happened.
Tested the touch screen, and everything passed.
Last night I noticed that it seemed to be related to the pressure I was putting on the screen, if I pressed down harder on the screen and slide my finger left or right or up the notification bar would come down. Did some more testing and for awhile I was able to reproduce it about 50% of the time. I rebooted the phone into safe mode (hold power button down and then press and hold the power off option for about 5 seconds it will ask if you want to reboot into safe mode). In Safe mode I could not reproduce it, Safe mode disables ALL third party apps.
WARNING: when I rebooted my phone to go back to "normal" all of my widgets and groupings were not on the screens, had to re add them.
After doing all this testing last night, I have not seen the notification come down, but like someone said it seems to get worse the longer the phone is running before reboot.
I was going to do a hard reset, today but that sounds like that may not help.
Not sure if this is software, but with the testing I did last night it seem to work fine in safe mode. However I have wondered if it is something with the screen, like is flexing enough for the sensors at the top to react to the pressure/flex.
Well keep testing and report back.

I'm also having some issues with the touch screen, but it mainly happens with the keyboard. I like to swipe to type, but lately I've noticed that it gets really jumpy, causing thing errors.
At first i thought it was touchpal so i installed Gboard. Problem still occurs.
I also removed my screen protector and tried did the touchscreen test.

I ran the line drawing test a bunch of times and yes, i now do see that mine fails to draw a continuous line on occasion. It only happens in the keyboard (squeezable?) area though.
I'm worried now that edge sense is damaging the touchscreen.

OK, i have ordered HTC u11 this morning from amazon, but i guess i will cancel my order. Had many problems with htc phones in the past. Saw many reviews and thought that this one is perfect with no flaws... Ahh..... Already ordered some accessories for my new device... It's really a shame to read this kind of threads. Hope you guys will find a solution and hope that this won't be a hardware issue.

Does your keyboard collapse when you are typing? That happens with me. Really frustrating when you are typing quite fast then the keyboard just disappears. Then you end up tapping a link or something that was behind the keyboard. You then need to go back to the page you were on and start typing all over again.

Are you running app killers? Stop boost+ auto. Apps updating from gplay can cause you to be kicked out of the keyboard, it can also pause/stop YouTube vids.
The edge sense system is 2 sensors stuck to the inside of the edge of the device, along the aluminium strips, they shouldn't interfere with the screen at any time.
Sweaty hands and greasy screen can cause the screen to misread your touches and gestures.
Running low on internal memory (sdcard) can cause all sorts of issues. Make sure you ALWAYS have a couple of Gb free.
Try to replicate the problem in test mode.

Personally I made sure to address all your points when trying to figure out what is going on. So none of this applies to me.

It doesn't collapse for me, but i do occasionally have the notification shade pulled down.

Same here, only I was told 7 to 15 business days. Offered to give c card to have a replacement shipped, but that is no longer an option with HTC.
So when I washed my M9, I was without a device for 2 days, but now that their phone is crap, it's going to be 3-4 weeks.
Unhappy....
